This project involves an upgrade at Portsmouth Naval Base, located in the South East of England. The future notice date for further information is set for 23rd February 2026, concluding with a contract period from 16th July to 16th December 2026. The procurement process initiates as a tender with an estimated value of £750,000 GBP, providing incentives for small and medium enterprises to partake in the process. The tender presents opportunities for businesses specialising in construction consultancies, especially those with expertise in maritime infrastructure projects. Ideal contenders include firms experienced in designing healing or strengthening quay structures, managing operations within naval environments, and executing construction-ready design packages. Equally beneficial would be organisations that adeptly navigate stakeholder interfaces involving defence clients or multi-disciplinary teams. This process not only opens doors for relevant businesses to expand their portfolio but also allows them to engage strategically with the Ministry of Defence at a high-profile naval base. SMEs are particularly encouraged to engage, facilitating substantial growth potential and noteworthy exposure in the sector. ## Notice This project involves developing the finalised Basis of Design into a full detailed design and construction ready package for the refurbishment of Berth 5B3 within Portsmouth Naval Base. The upgrade will provide enhanced operational capacity of the non-tidal basin at Portsmouth Naval Base. The design development progresses the scheme from RIBA Stage 2 to RIBA Stage 4, covering all civil and structural elements required for delivery. The scope includes strengthening and adapting the quay structures and access road to reinstate full operational capability at 5B3. As part of the qualification process we will be looking for evidence of; (Please refer to section 3.27 of the selection questionnaire) - Experience delivering RIBA Stage 2-4 design for major civil or maritime infrastructure projects. - Capability in quay wall, jetty, or berth structural design, including rehabilitation or strengthening of historic or mixed material waterfront structures. - Experience working within operational port, dockyard or naval environments, including managing constraints associated with security, access, and vessel movements. - Experience designing foundations and structural elements involving heritage or legacy construction, such as timber piles, stone walls, or hybrid masonry concrete structures. - Capability in producing construction ready design packages, including fully coordinated civil, structural, and access/roadway design. - Evidence of successfully managing stakeholder interfaces, particularly with infrastructure owners, defence clients, or complex multi disciplinary teams. - Experience delivering works where existing loading restrictions or degraded maritime structures require enhanced investigation, monitoring, or temporary works considerations.
